The Wagner Tuning Audi B5 RS4 Intercooler Kit is a high performance redesign of the original Audi OEM intercooler designed specifically for the B5 Enthusiasts. Our engineers have increased the intercooler core size and efficiency, as well as improved the end tank design to remove any OEM bottlenecks, resulting in increased flow rating and charge cooling properties.

This turbo recirculation valve is the result of of 25 years of experience and engineering expertise. With the reputation for innovating and manufacturing the best automotive valves in the world, you can be certain that there is currently no better replacement valve available.

All great products need a good foundation to build on. The B5 kit utilizes an industry first 30-way adjustable, monotube shock as the building block for the finest air suspension. These high performance shocks dissipate heat faster than twin tube shocks and provide more consistent damping during hard driving or bumpy road conditions. They also provide a significant range of damping within the adjustments so you can always find the sweet spot for your tastes.
